IMPROVEMENT IN PR'UNING IMPLEMENTS.

Specification forming part` of Letters Patent No. 131,703, datedSeptember 24, 1872.

To all whom it may concern:

'Be it known that I, JAMES REYNOLDs,of the city of Washington andDistrict of Columbia,have invented an Improved Pruning `l Vand TrimmingImplement; and I do hereby declare that the following, taken inconnection with the drawing which accompanies and forms part of thisspecification, is a description of my invention sufficient to enablethose rivets, so that it may be removed or replaced when needful, thecutter H, shaped like .a birds bill, and having its sharp cutting-edgeonthe under side. This serves of itself, without' any other cutter, fora great variety of trimming, by a mere pulling of the implement,

so that the blade may sever the twig or branch, the pulling movementbeing the easiest one `for the operator, and the most eicient ascompared with a pushing or a lateral movement, in either of which morepower is required and more lost. In conjunction with such blade I alsoemploy a downwardly-inclined sharp blade, B, on a stock, which is fittedby means of a slot, 2, therein, and a pin or screw, 3,011 the frame, toreciprocate in a straight line lengthwise of the implement, the samebeing pulled down or away from the blade by means of a rod, O, andconnecting-rod D, against the force of a powerful sprin g, 4, coiledwithin, and secured at its top to the cylinder or sheath E, throughwhich rod G passes. An eye, 5, on the handle F, serves to guide the rodor wire D, and a hook at the lower end of the latter serves to lock thetwo blades out of connection and joint action whenever they are notwanted to do the duty of shears. When acting as shears, however, thehook'is set free, and thus permits th'e blade B, after being pulled downand suddenly released, to fly with force toward the stationary blade andout off any intervening twig `or branch. The two cutting-edges occupysuch positions relatively to each other that in the motion of B incutting its edge traverses the edge of the cutter H and gives a sawingor shearing action upon the wood, and the greater curvature near the tipof the cutter H also prevents the wood from escaping from between theblades withoutlbeing severed. The cutter B is also removable at will,being .attached by screws. The saw Gr is riveted to the lower arm 6ofthe frame, and

at its other end to a plug, 7, which passes l through a socket, 8, on anoutward bend, 9, of the bow-frame A, ascrew-thread on the plug or bolt7, and a thumb-nut,10, serving to tighten the saw, as required.

I claim- The combination ofthe stationary bill-shape blade with theblade B, arranged to slide in right lines, and operated, when in the actof cutting, by the force of spring 4, as shown and described.
